Square Flanges Key Features

  • Can be attached to the pipe without welding (sometimes an additional seal weld is used as well)
  • Ideal for higher pressure and temperature applications for small pipe sizes
  • Not recommended for larger loads, especially when subjected to higher torque

NOTE: This flange is referred to as either threaded or screwed. It is used to connect other threaded components in low pressure, non-critical applications. No welding is required.
